Thought I would mention that at the 2017 Eureka Springs Corvette Weekend, I drove my 1993 #180 to victory in the Fuel Economy Run with and average of 42.4 miles per gallon. I beat my former record set in 2015 driving my 2015 C7 coupe automatic by 1 tenth of a gallon per mile.
The ZR-1 is still King of the Hill, LOL
